By default, the Makerkit kits come with a light and a dark theme, and we provide a toggle to let users switch between them.

## Changing the default theme

To change the default theme, you need to update the theme in your `src/configuration.ts` file.

 ```ts {% title="src/configuration.ts" %} {2}
const configuration = {
  theme: Themes.Dark,
  ...
}
```

## Disabling the theme toggle

To disable the theme toggle, you need to update the `src/configuration.ts` file.

 ```tsx {% title="src/configuration.ts" %} {3}
const configuration = {
  theme: Themes.Dark,
  features: {
    enableThemeSwitcher: false,
  },
  ...
}
```

This will prevent the theme toggle from appearing in the application.
